NH4I will completely dissolve in ammonium and iodide ions: of which I-is neutral and NH4+ is quite a weak acid (pKa = 9.25). (The molar standard solution of NH4I will have pH approx. 4.6).
Water is also central to acid-base neutrality and enzyme function. An acid, a hydrogen ion (H + , that is, a proton) donor, can be neutralized by a base, a proton acceptor such as a hydroxide ion (OH â) to form water. Water is considered to be neutral, with a pH (the negative log of the hydrogen ion concentration) of 7.
